FOLDING COT-BED.

SPECIFICATION forming part of Letters Patent No. 409,262, dated August 20, 1889.

Application filed March 6, 1889. Serial No, 302,160% (No model.)

T0 all whom, t may concern:

Be it known that I, GEORGE II. IVILSON, of Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Folding Cot-Beds; and I do hereby declare that the following is a full, clear, and exact description of the invent-ion, which will enable others skilled in the art to which it appertains to make and use the same, reference being' had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this speciiication.

My invention relates to folding cot-beds; and the objects of my invention are, first, to provide a folding bolster for this class of beds which shall be automatically moved into position when the legs of the bed are extended and automatically folded down when the legs are turned up under the cotframe; also, to provide means for retaining the legs in extended position and for straining the canvas bottom of the bed; and, iinally, for firmly securing the edges of the canvas bottom to the side rails of the bed-frame in such manner as to prevent all possibility of tearing the fabric.

To the above purposes my invention consists in certain peculiar and novel features of construction and arrangement, as hereinafter described, and pointed out in the claims.

In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which similar letters of reference designate similar parts, and in which also-- Figure l is a side elevation of a cot-bed with my improvements applied thereto. Fig. 2 is an end elevation of the same looking at the head of the bed. Fig. 3 is a central longin tudinal section of the bed shown in Fig. l. Fig. et is a view showing the bed folded up. Fig. 5 is a cross-section of one of the side rails, showing the arrangement for securing the edges of the canvas bottom. Fig. G is an end vie-W of one of the bolster-frames. Fig. 7 is a sectional view on the line A B of Fig. 3.

In the said drawings, l designates the side rails of the bed.

2 designates the pair of legs which support the head end of the bed, and 3 the pair of legs which support the foot end of the same, said legs being pivoted at their upper ends to the inner sides of the rails l, as shown at l and l", respectively. Between each pair of legsl and 2 are placed a series of folding braces, as best shown in Fig. 2. As will be seen by reference to this figure, two braces 3 and 3d are pivoted together at their inner ends midway between the two legs, and the outer ends of said braces are pivoted at 3b and 3 upon the upper parts of said legs. Two braces et and 5 are pivoted upon the lower parts of the legs at Il and 5, and the inner end of the brace 4L is pivoted upon the brace 5 at a point 5b midway between the legs; but it will be observed that the brace 5 is longer than the brace i and extends'beyond the point at which the brace e is connected to it. The extremity of this extended portion of brace 5 is pivoted'in a beyond its inner end, as shown. p of this arrangement is that when the sidesmof the bed are separated the braces 3b dvrest at their inner ends upon the upper side of the brace 5, and thus lock all of thefbraces and form a firm support for the `legs while also tightly straining the canvasw` G 6 designate two bars which constitute the bolster-frame of the bed, and to which the upper or head portion of the canvas bottom is secured, as hereinafter more particularly described. These bars G are pivoted to the side rails l at the points 7, and are connected to the legs i by hooks 8, as best shown in Fig. 7, which engage or are pivoted in the legs at a point a little below where the leg is pivoted to the side rail. The straight portion or body 0 of hooks 8 is considerably elongated, and said body portions slide in grooves 10, which extend longitudinally of the bolster-frames G. As the hook 8 engages the leg below its pivotal point, it is evident that as the leg is folded by turning on its pivot the shank of the hook 8 will be partially drawn out of the groove in the bolster-frame, and as it passes around the pivotal point of the leg and into line with the side rail the bolster-frame is automatically operated therewith and folded thereby. The-washers 1l of the pivots 7 serve to retain the hook stems or bodies within the grooves 10. It will also be seen, by reference to Figs. l and 3, that the inner or lower ends slot `1S, upon the opposite brace 3, at a point 7p The resiilft"1 IOC of bolster-frames 6 serve as braces to support the legs 2 when they are extended.

The legs 3 at the foot of the bed are braced when extended by bars 12, which are pivoted at one end to the side rails 1, and which are connected to the legs 3 by hooks 14, working in longitudinal grooves in said bars 12, similarly to the hooks 9, before described, and retained in said grooves by staples 13. (See Fig. 3.) It will be observed that when the legs 3 are extended the lower ends of the bars 12 serve as braces to support said legs.

In order to firmly secure the edges of the canvas bottom 15 (see Fig. 5) to the side rails 1, elongated dovetail grooves 16 are formed in the sides of said rails, and the edges of the canvas bottoms are retained Within said grooves by elongated metal strips 17, which are driven in endwise from the ends of the grooves 16. A similar arrangement is employed in connection with the bolster-frames 6. The fabric bot-tom 15 in the construction shown extends in one piece from the foot of the cot to the head of the bolster-frame, although it is evident that a separate piece of fabric might be used upon the bolster-frame- It will thus be seen that a simple, strong, and durable form of cot-bed is produced, which is readily set up and folded, and that the canvas bottom is securely held lto the frame without beingperforated, and consequently avoiding all possibility of rupturing or tearing the edges of the bottom. It Will also be seen that the bolster-frame is automatically raised and lowered by extending and folding up the legs 2, and that the canvas bottom is equally strained throughout.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a cot-bed, the combination, with the oppositely-disposed legs, of the interlockingbraces 3, 3d, 4, and 5, each of which is pivoted at one extremity to the legs and the braces 3a and 3d to each other, and 3d having a slotted opening 1S, and the braces 4 and 5 pivoted to each other at 5b, and the brace 5 engaging 3a in the slotted opening therein, substantially as set forth.

2. In a cot-bed, the combination, with the side rails and the folding legs, of the bolsterframes pivoted to the side rails, and hooks sliding in the bolster-frames and connecting the latter to the legs, substantially as described.

3. In a cot-bed, the combination, with the folding legs, of pivoted bars secured to the side rails and serving as braces for the legs, and hooks connecting the legs and bars and sliding in grooves in the latter, substantially as described.

In Witness whereof I have affixed my signature in presence of two Witnesses.

GEO. H. WILSON.
